    Product Description

    25-hydroxy Vitamin D3 is an intermediate in the pathway leading to the production of 1,25-dihydroxy vitamin D3, the most receptor-active form of vitamin D. 25-hydroxy Vitamin D3, produced in the liver from vitamin D3, is metabolized in the kidney to 1,25-dihydroxy vitamin D3. Plasma or serum levels of 25-hydroxy vitamin D3 are commonly used as an indicator of an individual’s vitamin D status.1
